VSEP
a Key Component of the WateReuse Foundation’s
2009 Desalination Project of the Year

Emeryville, CA (10/05/2009) – Situated
in the rolling hills of Northern California’s
Capay Valley, Cache Creek Casino Resort is a
model of sustainability. Owned and operated by
the Yocha Dehe Wintun Nation, the tribe has made
harmony with the land a top priority in all aspects
of its resort operations. Naturally, that approach
applies to its on-site water treatment facility.

A new 18-hole golf course increased the resort’s
water needs, but with groundwater high in salts,
silica, and hardness, a novel treatment solution
was necessary. To that end, the tribe enlisted
the help of HydroScience Engineers to design
and engineer a system to treat the groundwater
while minimizing waste.

While desalination was relatively easy to come
by, brine management would prove to be more challenging.
Hydroscience turned to trusted partner Aquadyne
Associates, who recommended New Logic’s
Vibratory Shear Enhanced Process (VSEP) as an
elegant method of brine minimization. Pilot studies
were carried out to verify the feasibility of
the application, and the data proved VSEP would
achieve the necessary volume reduction while
maintaining permeate quality suitable for reuse.

Cache Creek’s 650,000 gallon per day
desalination plant is now fully operational and
consists of a cloth prefiltration system
to remove suspended solids, an electrodialysis
reversal system (EDR) to remove salts and hardness,
and a VSEP vibrating membrane system to reduce
the EDR brine volume. The VSEP system is able
to recover 90% of the EDR brine as clean water
for reuse, thus increasing overall recovery and
dramatically reducing brine hauling costs.

The Cache Creek desalination facility has caught
the attention of industry leaders, and has been
awarded the 2009 WateReuse Desalination Project
of the Year for its unique approach to treating
a difficult source water.

"Water management and brine disposal is
becoming an increasingly important issue in California.
With less water to go around in for farmers and
industry, people are increasingly turning to
secondary water sources. Just as the trend is
toward alternative energy sources, the future
in California will require alternative water
sources, and we’re proud to be on the ground
floor of this effort," says New Logic Research
CEO, Greg Johnson.
